Hello, my fellow Lebanese. It’s me, your friendly Green Patriot. Did any of you see the television commercial yesterday on conserving water? It’s true, we do need to conserve water. Luckily for us, as a country that has rain, we can do that.

Rain harvesting allows us to accumulate, treat,  and store rainwater for reuse. This method has been used to provide drinking water, water for livestock, water for irrigation, as well for menial things such as cleaning, etc. Although it needs to be treated before use, it can supplement groundwater in this fashion, and make a large difference in the amount of usable water available to us.

This is done in a very basic manner. Rainwater is collected from the roofs of buildings, and it runs through a basic system that cleans it and makes it appropriate for use. Household rainfall catchment systems are appropriate in areas with an average rainfall greater than 200 mm (7.9 in) per year. Lebanon is one such country. A typical rainwater harvesting system meant to supplement groundwater looks like this:

There are other rain harvesting structures that do not flow into the soil if the water is meant for other purposes (cleaning, etc.) Designing a rain harvesting structure is based on your needs!

At present, out of our 8 billion six hundred thousand cubic meters of rain, only one billion is being used. Lebanon, we have the potential to use our rainwater to our advantage! This system is inexpensive to implement, and would save us both money and resources, regardless as to whether or not we implement it in our homes, in our water companies, or on public level by the government. We have the technology and the rainwater potential to do so. We can do it, Lebanon!
